Description

L'invention concerne un enrouleur pour sangle, cordon ou analogue.The invention relates to a winder for a strap, cord or the like.

Les systèmes de descente ou de remontée de volets de fenêtres peuvent être équipés d'enrouleurs de sangle, de cordon ou analogues reliés au volet et permettant, par une traction vers le bas, de relever le volet, ou par une action de relâchement de la tension de la sangle ou du cordon, la remontée de la sangle ou du cordon et la descente du volet. Les enrouleurs sont formés d'un boîtier incluant un dispositif d'enroulement à ressort, ainsi qu'une bride et une goupille formant un système permettant le guidage de la sangle ou du cordon dans le boîtier, et le freinage de la sangle ou du cordon par pincement de cet élément entre la bride et la goupille en position intermédiaire du volet.The systems for lowering or raising window shutters may be equipped with strap winders, cord or the like connected to the shutter and allowing, by pulling downward, to raise the shutter, or by a release action of the shutter. Tension on the strap or cord, raising the strap or cord and lowering the flap. The reels are formed of a housing including a spring winding device, and a flange and pin forming a system for guiding the strap or cord in the housing, and braking the strap or cord. by pinching this element between the flange and the pin in the intermediate position of the flap.

Les enrouleurs doivent être démontables pour les opérations de maintenance. Différentes solutions techniques, notamment décrites dans EP 0 812 795 , EP 1 001 131 ou EP 1 059 415 utilisent des boîtiers formés de deux parties solidarisées le long d'un plan médian, et pouvant être ouvertes de manière à donner accès à l'intérieur du boîtier.The reels must be dismountable for maintenance operations. Different technical solutions, notably described in EP 0 812 795 , EP 1 001 131 or EP 1 059 415 use housings formed of two parts secured along a median plane, and can be opened to give access to the inside of the housing.

L'inconvénient de ces systèmes connus provient du fait que les éléments tels que les dispositifs d'enroulement à ressort, la bride et la goupille sont directement accessibles à l'ouverture du boitier et donc susceptibles de se démonter et de provoquer des dysfonctionnements de l'enrouleur, ou bien même des accidents si le ressort du dispositif d'enroulement est projeté en dehors du boîtier. En outre, des mauvaises manipulations résultant de l'ouverture du boîtier par une personne non habilitée peuvent survenir.The disadvantage of these known systems stems from the fact that elements such as spring winding devices, the flange and the pin are directly accessible to the opening of the housing and therefore likely to disassemble and cause malfunctions of the housing. winder, or even accidents if the spring of the winding device is projected outside the housing. In addition, improper handling resulting from the opening of the housing by an unauthorized person can occur.

GR 2009 0100 326 décrit un système d'enrouleur pour sangle, cordon ou analogue, comprenant un boitier ayant une partie fixe et une partie amovible, dont le démontage permet d'accéder à un dispositif d'enroulement monté dans la partie fixe. Le dispositif d'enroulement à ressort n'est pas maintenu car le retrait de la partie mobile donne la possibilité de retirer le dispositif d'enroulement. GR 2009 0100 326 discloses a winding system for a strap, cord or the like, comprising a housing having a fixed portion and a removable portion, the disassembly of which provides access to a winding device mounted in the fixed part. The spring winding device is not maintained because the removal of the moving part gives the possibility of removing the winding device.

C'est à ces inconvénients qu'entend remédier l'invention en proposant un nouvel enrouleur de sangle, cordon ou analogue, permettant une ouverture du boîtier sécurisée et évitant les erreurs de manipulation.It is these drawbacks that the invention intends to remedy by proposing a new strap winder, cord or the like, allowing the casing to be opened securely and avoiding handling errors.

A cet effet, l'invention concerne un enrouleur pour sangle, cordon ou analogue, comprenant un boitier englobant un dispositif d'enroulement à ressort de la sangle ou du cordon, et un système de guidage et de freinage de la sangle ou du cordon, le boitier comprenant une première et une seconde parties solidarisées l'une à l'autre autour d'un plan médian de l'enrouleur parallèle à des faces latérales du boitier, le dispositif d'enroulement comprenant une pièce d'accrochage de la sangle ou du cordon. Cet enrouleur est caractérisé en ce que la première partie du boitier comprend un élément mobile et un élément non mobile, l'élément mobile étant mobile par rapport à l'élément non mobile et par rapport à la seconde partie entre une position fermée, dans laquelle aucun accès n'est possible à l'intérieur du boitier, et une position ouverte, donnant accès à une zone du boitier dans laquelle se trouve la pièce d'accrochage, et en ce que l'élément non mobile est fixé de manière inamovible à la seconde partie du boitier et forme une zone non accessible du boitier dans laquelle est situé le système de guidage et dans laquelle le dispositif d'enroulement à ressort est maintenu de telle manière que son axe central est immobile dans le plan médian de l'enrouleur et que le dispositif d'enroulement à ressort ne peut sortir du boitier.To this end, the invention relates to a winder for a strap, cord or the like, comprising a casing including a spring winding device of the strap or cord, and a guide and braking system of the strap or cord, the housing comprising a first and a second portion secured to one another around a median plane of the winder parallel to lateral faces of the housing, the winding device comprising a fastening part of the strap or cord. This retractor is characterized in that the first part of the housing comprises an element mobile and a non-moving element, the movable element being movable relative to the non-movable element and relative to the second part between a closed position, in which no access is possible inside the housing, and a open position, giving access to an area of the housing in which the attachment piece is located, and in that the non-movable member is fixed irremovably to the second portion of the housing and forms a non-accessible area of the housing in which is located the guide system and wherein the spring winding device is held such that its central axis is stationary in the median plane of the winder and that the spring winding device can not out of the housing.

Grâce à l'invention, la goupille et la bride ne peuvent pas être atteintes par une personne ouvrant le boîtier, ce qui évite leur démontage et de potentiels dysfonctionnements de l'enrouleur. En outre, seule la pièce d'accrochage de la sangle est accessible par l'ouverture du boîtier, le dispositif d'enroulement lui-même restant fixé dans le boîtier, ce qui évite d'éventuels désagréments liés à la sortie du ressort du dispositif d'enroulement.Thanks to the invention, the pin and the flange can not be reached by a person opening the housing, which prevents disassembly and potential malfunctions of the reel. In addition, only the attachment part of the strap is accessible through the opening of the housing, the winding device itself remaining fixed in the housing, which avoids any inconvenience related to the output of the device spring winding.

The end of the strap is then pierced so as to be engaged on the hook 50.

Pour une telle opération, l'accès à l'intérieur du boîtier 3 doit être permis. A cet effet, la première partie 3a comprend un élément mobile 3a1 et un élément non mobile 3a2. L'élément mobile 3a1 est mobile par rapport à l'élément non mobile 3a2 entre une position fermée, correspondant à une configuration d'utilisation de l'enrouleur 1 représentée aux figures 1 et 2, et une position ouverte, correspondant à une configuration de maintenance, représentée à la figure 5. Dans la position fermée, aucun accès n'est possible à l'intérieur du boîtier 3. Dans la position ouverte, l'ouverture de l'élément mobile 3a1 créé un espace par rapport à la seconde partie 3b, qui donne accès à une zone Z1 du boîtier 3 dans laquelle se trouve le crochet 50. Cet accès à la zone Z1 permet à un opérateur voulant changer la sangle, de démonter la sangle initialement présente, d'engager une sangle neuve à l'intérieur du boitier 3 par l'ouverture 30, et de saisir la sangle neuve à l'intérieur du boîtier 3 et de l'engager sur le crochet 50, tout en prenant soin lors de ces opérations de maintenir la tension du ressort du dispositif d'enroulement 5.For such an operation, access to the interior of the housing 3 must be allowed. For this purpose, the first part 3a comprises a movable element 3a1 and a non-movable element 3a2. The movable element 3a1 is movable relative to the non-movable element 3a2 between a closed position, corresponding to a configuration of use of the reel 1 shown in FIGS. Figures 1 and 2 , and an open position, corresponding to a maintenance configuration, shown in FIG. figure 5 . In the closed position, no access is possible inside the housing 3. In the open position, the opening of the movable element 3a1 creates a space with respect to the second part 3b, which gives access to a zone Z1 of the housing 3 in which is the hook 50. This access to the Z1 zone allows an operator wanting to change the strap, to disassemble the strap initially present, to engage a new strap inside the housing 3 by the opening 30, and to grip the new strap inside the housing 3 and engage it on the hook 50, taking care during these operations to maintain the tension of the spring of the winding device 5.

L'élément non mobile 3a2 est fixé de manière inamovible à la seconde partie 3b, de manière à définir une zone Z2 non accessible du boîtier 3, dans laquelle sont situées la bride 7 et la goupille 9 formant le système de guidage et de freinage, et dans laquelle le dispositif d'enroulement 5 est maintenu c'est-à-dire que son axe central X5, perpendiculaire au plan médian P1, qui correspond à l'axe de rotation du dispositif de d'enroulement 5, reste immobile selon ce plan. L'élément non mobile 3a2 est de préférence monté serré en usine sur la seconde partie 3b.The non-movable element 3a2 is immovably attached to the second part 3b, so as to define an inaccessible zone Z2 of the housing 3, in which are located the flange 7 and the pin 9 forming the guiding and braking system, and in which the winding device 5 is held, that is to say that its central axis X5, perpendicular to the median plane P1, which corresponds to the axis of rotation of the winding device 5, remains stationary according to this plan. The non-movable member 3a2 is preferably mounted tightly in the factory on the second portion 3b.

L'élément non mobile 3a2 présente une paroi 3a20 qui s'étend parallèlement au plan médian P1 au-dessus de la bride 7 et de la goupille 9 et en partie au-dessus du dispositif d'enroulement 5. Cette paroi 3a20 masque en partie le dispositif d'enroulement 5 et en totalité la bride 7 et la goupille 5. La bride 7 et la goupille 9 ne peuvent donc pas sortir du boitier perpendiculairement au plan médian P1. Le dispositif d'enroulement 5 ne peut pas non plus sortir du boitier perpendiculairement au plan médian P1 du fait du masquage par la paroi 3a20 ni parallèlement au plan médian P1 du fait de la présence d'une forme d'accueil 3b3 du dispositif d'enroulement 5 présente dans la seconde partie 3b. La forme d'accueil 3b3 est formée par une nervure globalement circulaire en saillie de la face interne de la seconde partie 3b, adaptée pour entourer un axe central non visible du dispositif 5.The non-movable element 3a2 has a wall 3a20 which extends parallel to the median plane P1 above the flange 7 and the pin 9 and partly above the winding device 5. This wall 3a20 partially masks the winding device 5 and the entire flange 7 and the pin 5. The flange 7 and the pin 9 can not leave the housing perpendicularly to the median plane P1. The winding device 5 can not leave the box perpendicularly to the median plane P1 because of the masking by the wall 3a20 nor parallel to the median plane P1 because of the presence of a form of reception 3b3 of the device. winding 5 present in the second part 3b. The form of reception 3b3 is formed by a generally circular rib projecting from the internal face of the second part 3b, adapted to surround a non-visible central axis of the device 5.

La paroi 3a20 comprend une zone de montage 3a22 dans laquelle le dispositif d'enroulement 5 est monté. Le dispositif d'enroulement 5 comprend un élément de fixation 52 adapté pour s'emboîter dans la zone de montage 3a22 par coulissement. L'élément de fixation 52 porte un arbre de rotation non représenté du dispositif d'enroulement 5, s'étendant selon l'axe X5. L'élément de fixation 52 se prolonge en une pièce de blocage 54 dont la fonction est, comme cela est représenté sur les figures 4 et 6, d'empêcher l'enroulement de la sangle en bloquant en position le crochet 50. La pièce de blocage 54 est adaptée pour être rompue par cassage du lien avec l'élément de fixation 52, de manière à libérer la force d'enroulement du dispositif d'enroulement 5.The wall 3a20 comprises a mounting zone 3a22 in which the winding device 5 is mounted. The winding device 5 comprises a fastening element 52 adapted to fit into the mounting zone 3a22 by sliding. The fixing element 52 carries a not shown rotation shaft of the winding device 5, extending along the axis X5. The fastening element 52 is extended into a locking piece 54 whose function is, as is shown in FIGS. figures 4 and 6 to prevent the winding of the strap by locking the hook 50 in position. The locking piece 54 is adapted to be broken by breaking the connection with the fastening element 52, so as to release the winding force of the winding device 5.

L'élément mobile 3a1 est solidarisé à la seconde partie 3b par des pattes 3a10 prévues sur une face interne de l'élément mobile 3a1, logées dans des pinces 3b1 prévues sur une face interne de la seconde partie 3b, les pinces 3b1 exerçant un effort élastique sur les pattes 3a10. Selon une variante non représentée, les pattes 3a10 peuvent être implantées sur la seconde partie 3b, tandis que les pinces 3b1 peuvent être implantées sur l'élément mobile 3a1.The movable element 3a1 is secured to the second part 3b by lugs 3a10 provided on an inner face of the movable element 3a1, housed in clamps 3b1 provided on an inner face of the second part 3b, the clamps 3b1 exerting a force elastic on the legs 3a10. According to a variant not shown, the tabs 3a10 may be implanted on the second part 3b, while the clamps 3b1 may be implanted on the movable member 3a1.

L'élément mobile 3a1 est articulé en rotation par rapport à l'élément non mobile 3a2 par deux doigts 3a24, prévus sur l'élément mobile 3a1, et insérés dans deux gorges 3a12 de forme circulaire prévues dans l'élément mobile 3a1. Les doigts 3a24 sont prévus du côté interne de l'élément non mobile 3a2, et les gorges circulaires 3a12 sont prévues sur des pattes 3a13 situées en retrait, vers l'intérieur du boitier 3, de la face interne 3a11 de l'élément mobile 3a1, de sorte que le mécanisme de pivot entre l'élément mobile 3a1 et l'élément non mobile 3a2 est entièrement située à l'intérieur du boitier 3 et reste donc invisible sur le côté externe de l'enrouleur 1, ce qui évite des manipulations et l'ouverture fortuite de l'enrouleur 1 par du personnel non qualifié.The movable member 3a1 is articulated in rotation relative to the non-movable member 3a2 by two fingers 3a24, provided on the movable member 3a1, and inserted into two grooves 3a12 of circular shape provided in the movable member 3a1. The fingers 3a24 are provided on the inner side of the non-movable member 3a2, and the circular grooves 3a12 are provided on lugs 3a13 set back, towards the inside of the case 3, of the internal face 3a11 of the movable member 3a1. , so that the pivot mechanism between the movable element 3a1 and the non-movable element 3a2 is entirely located inside the housing 3 and remains invisible on the outer side of the winder 1, which avoids manipulations and the accidental opening of the reel 1 by unqualified personnel.

Afin de guider la sangle lors de son insertion dans le boîtier 3 vers le crochet 50, des nervures courbées sont prévues dans l'intérieur du boîtier 3. Ces nervures courbées sont formées par des portions de nervures 3b2 prévues sur une face interne de la seconde partie 3b et des portions de nervures 3a26 sur une face interne de l'élément non mobile 3a2. Selon une variante non représentée de l'invention, une seule des parties 3a et 3b peut comporter des nervures de guidage de la sangle.In order to guide the strap when it is inserted into the housing 3 towards the hook 50, curved ribs are provided in the interior of the housing 3. These curved ribs are formed by portions of ribs 3b2 provided on an inner face of the second part 3b and portions of ribs 3a26 on an inner face of the non-movable member 3a2. According to a not shown variant of the invention, only one of the parts 3a and 3b may comprise ribs for guiding the strap.

Lors du montage d'une sangle ou bien du remplacement d'une sangle, un opérateur procède donc de la manière suivante. Pour ouvrir le boitier 3, l'opérateur exerce une pression sur l'élément mobile 3a1 selon la flèche F1 de manière à dégager une languette 3a16 prévue sur le bord 3a14. Ensuite, l'opérateur exerce une rotation de l'élément mobile 3a1 selon la flèche R1, par rapport à l'élément non mobile 3a2 et à la seconde partie 3b, de manière à désengager les pattes 3a10 des pinces 3b1 et permettre l'accès à la zone Z1. L'opérateur peut ensuite enlever la sangle existante si présente tout en prenant soin de maintenir la tension du ressort du dispositif d'enroulement 5, puis engager une nouvelle sangle par l'orifice 30. La sangle est guidée par les nervures 3b2 et 3a26 vers la zone Z1, dans laquelle l'opérateur peut s'en saisir et l'accrocher sur le crochet 50 après avoir préalablement percé l'extrémité de la sangle. Si aucune sangle n'était présente, l'opérateur casse alors la pièce de blocage 54, permettant ainsi l'enroulement de la sangle autour du dispositif d'enroulement 5. Le boitier 3 peut ensuite être refermé par remise de l'élément mobile 3a1 dans sa position fermée. A aucun moment de l'opération le dispositif d'enroulement 5, la bride 7 et la goupille 9 ne courent le risque de sortir du boitier 3.When mounting a strap or the replacement of a strap, an operator proceeds in the following manner. To open the housing 3, the operator exerts pressure on the movable member 3a1 along the arrow F1 so as to release a tongue 3a16 provided on the edge 3a14. Then, the operator rotates the movable member 3a1 along the arrow R1, relative to the non-movable member 3a2 and the second portion 3b, so as to disengage the legs 3a10 of the clamps 3b1 and allow access to zone Z1. The operator can then remove the existing strap if present while taking care to maintain the tension of the spring of the winding device 5, then engage a new strap through the hole 30. The strap is guided by the ribs 3b2 and 3a26 to zone Z1, in which the operator can grab it and hang it on the hook 50 after having previously pierced the end of the strap. If no strap was present, the operator then breaks the locking piece 54, thus allowing the winding of the strap around the winding device 5. The housing 3 can then be closed by handing the movable member 3a1 in its closed position. At no time of the operation the winding device 5, the flange 7 and the pin 9 run the risk of leaving the housing 3.
